In the field of tension between economics, aesthetics and usefulness, the two artists have developed a consistently reduced anti-concept. For the project INTERFUSION they penetrate urban and natural environments with artificial light and accentuate the sub-spaces therein. The light is the activist, which produces a high degree of rhetorical expressio n using minimal amounts of electricity. The two artists present large-scale images in a series of choreographic light installations, implemented in contemplative places where light installations may want to be, but cannot be.
